NanoQuest Spectral Sensor

NanoQuest is a compact new spectral sensor for qualification and quantification of materials from 1350-2500 nm. Its performance is comparable to laboratory-based spectrometers, but at dramatically smaller size and lower cost.

NanoQuest is based on Fourier transform infrared (FT-IR) technology, which is often favored in laboratory spectrometers because it collects spectral data over a wide range. The sensor’s patented micro-electro-mechanical systems (MEMS) technology allows for a continuous-wave Michelson interferometer to be created monolithically on a MEMS chip. This enables detection of all wavelengths simultaneously, and mitigates the effects of motion on sensor stability.


NanoQuest Advantages

  • Covers wider spectral range (1350-2500 nm), at lower cost, than other shortwave IR instrumentation

  • Ultra-compact size (smaller than a deck of playing cards) frees up bench space and makes scalability simpler

  • User-selectable optical resolution (8 nm or 16 nm FWHM) and scan rate provide experiment flexibility

  • Versatile setup options enable absorbance/transmission or reflectance measurements

  • Wider range and lower cost make access to shortwave IR measurements more manageable for a greater number of researchers

NanoQuest Example Applications

  • Authentication – identification of counterfeit textiles, polymers
  • Biomedical and Life Sciences – analysis of bodily fluids, hair samples
  • Food and Agriculture – soybean screening; measurement of sugar content in cereals; raw milk analysis; monitoring nutrients in soil, feed and leaves
